VW Touareg
Solid V6 common-rail diesel with good refinement, but known timing chain weakness and tendency to EGR fouling. Plastic coolant circuit components age and can lead to head gasket failure β always take coolant loss seriously immediately.
Confident touring V6
The CRCA with 245 hp moves the Touareg II with appropriate refinement β a cultured long-distance companion.
Engine Weaknesses 5
The 3.0 V6 TDI tends to chain stretch with metallic rattling from cold start. Noticeable particularly between 80,000 and 160,000 km. Chain tensioner responds positively to frequent oil changes with better oil.
Symptoms: Metallic rattling from the engine bay on cold start, especially at 1,800β2,100 rpm
A plastic connector between the EGR cooler and coolant shut-off valve breaks over time. Minimal coolant loss is often ignored β until the head gasket burns through and water enters the combustion chamber.
Symptoms: Slight coolant loss without visible leak, fluctuating coolant temperature, occasional white exhaust plume
Faulty injectors cause rough running, increased consumption and smoke. Individual injectors cost 300β600 β¬ plus labour; total failure of all six exceeds 3,000 β¬.
Symptoms: Rough engine, increased consumption, smoking, hard knocking, quantity corrections on individual cylinders
A plastic part costing 20β30 β¬ between the EGR cooler and the coolant shut-off valve breaks and causes massive coolant loss. Leads to head gasket failure.
Symptoms: Coolant loss without visible leak, temperature spikes to 130Β°C, engine not running on all cylinders, white smoke
The EGR valve clogs with oil and soot on short trips. Power loss and rough idle result. Cleaning helps temporarily; with heavy fouling replacement is necessary.
Symptoms: Fluctuating idle speed, power deficit in the lower rpm range, sluggish throttle response
Vehicle Weaknesses 15
Same system weakness as the predecessor: the 40A relay seizes after 3β4 years; condensate ice blocks the compressor in winter. Compressor overheating can be dangerous. Compressor replacement: 400β1,500 β¬.
CAN bus communication faults cause the simultaneous failure of multiple systems (reversing camera, ACC, towing module, start-stop). Often caused by a faulty trailer control unit J345 or insufficient battery voltage.
On the Touareg 7P, the ball bearing at the front axle output of the transfer case wears due to insufficient lubrication in the ZF transfer case. Repair requires approx. 10 hours of workshop time.
Brake discs wear out prematurely on the heavy Touareg 7P, sometimes after just 30,000β40,000 km. Full brake service (front and rear axle) costs approx. 2,800 β¬. The electric parking brake requires software tools for pad changes.
Electric parking brake fails to release or shows fault messages. The cause is defective actuator switches or actuator motors. Repair: 300β800 β¬. Software tools are essential for pad changes.
Seals between the longitudinal and transverse drain channels of the panoramic roof fail, especially on 2015 model year vehicles. Water penetrates and rusts internal metal carriers. Frame replacement can cost up to β¬1,600.
Adaptive cruise control and Front Assist regularly drop out and show 'unavailable'. Often caused by a dirty or misaligned radar sensor. Radar sensor replacement costs over 2,000 β¬.
Rust forms in the door flanges and at door inner edges, particularly on the tailgate. Paint undermining creates visible blisters. Less common than on the predecessor, but documented on older 7P models.
The automatic gearbox shows irregular shift behaviour and oil loss at higher mileages. Regular gearbox oil changes (every 60,000 km) are important. Gearbox overhaul: 3,000β6,000 β¬.
The rubber bearing in the rear propshaft ages and cracks as the rubber becomes brittle through weathering. VW only supplies the complete propshaft β individual centre bearing replacement is not factory-supported.
On the Touareg 7P, the water drain hose in the rear wheel arch detaches from its holder. Water runs directly into the spare wheel well instead of outside. The hose can be permanently secured with cable ties.
The panoramic glass roof creaks especially on the motorway due to play in the sliding rails. Acid-free synthetic grease on the rails usually resolves the problem.
Vienna leather seats show wear-through on the driver's seat surface after approx. 2β3 years. Leather quality is considered a weak point, although the interior overall is regarded as high quality.
On the Touareg 7P with 4-zone climate control, the blower motor in the boot (left side) fails. Cause is worn carbon brushes or a defective PWM control unit. The installation position makes repair labour-intensive.
On the Touareg 7P with electric tailgate, the drive motor fails. The tailgate doesn't respond to the switch, key, or interior button. Failing gas struts increase the load on the motor further.
